Stupid rubber.Bought these Blackfins, they're great sunglasses. Sent them in for a lense repair, Costa was very timely about this. Got them back and wore them for a few months, rubber started coming off. What the heck is the point of putting rubber around the inside of sunglasses when it doesn't really hold them to your head? Not very happy with these because of the rubber mess on them.

Best FramesI have five different pairs of blackfins. With the new injection molding these are by far my favorite glasses. I also have a pair of cuts, wingmans, corbinas, tuna alleys, double haul, isabellas, south point, cudjoes and a few others. Just wish costa would bring back the gunmetal frame for the blackfins. I'm a walking promotion and will never purchase another brand of sunglasses. Thanks Costa Crew!
